Yet Another Befunge Page

What is Befunge?

It's fun. It's free. It's eminently two-dimensional. And
unfortunately, most information about it is accessible only via the
Wayback
Machine.

Documentation

I've been attempting, off and on, to compile as much information
as I can about Funge-98 and its predecessors (and successors).
One of these days, I'll make another try at a standard-compliant
Funge-98 interpreter. Some of my old notes on Funge-98 are in
this document.

The Fungus Virtual Machine

Several years ago, Alexios
Chouchoulas wrote a paper describing Fungus, a physical machine
especially designed for the Funge programming paradigm. I have a
software implementation of that specification, with some useful
extensions; and also a two-dimensional assembler for creating binary
programs to run on the virtual machine.
